The mind can only do so much in a given time, and for one mind to analyze a tremendous body of data can be overwhelming. Therefore, our minds unconsciously turn to an age-old method called oversimplification in order to make sense out of the confusion. This is NOT ACCEPTABLE for predicting the future, and we must try our best to make our future timeline as complex as possible and as complete as possible, for there will always be things left out. A manifestation of this is the Single Advancement Problem, the tendency of forecasters to tacitly assume that only one significant technological change will happen in society, but meanwhile everything else will stay same as it is right now.
